6 Claims.

This invention relates to a carton for packaging articles so as to 'be visible while in the package. An important object of this invention is the provision, in a manner as hereinafter set forth,

of a carton designed to be quickly and easily assembled, and so formed that 'upon being lled with the commodities to be sold, the articles willber walls terminating Yat each end in flap members de- Y signed to interlock with the adjacent end iiap member to hold the side walls and the first mentioned iiaps of the carton in upright position. When the carton is thus assembled articles for they are visible. s

A further object of this invention is the pro,-

vision of a carton made from a single blank havinga transparent window for displaying the goods Within the carton, the said carton being shipped in fiat knocked-downj condition to the user.

'The invention will be best understood from a consideration of the following detailed description taken in connection with/the accompanying drawf ings forming apart of this specification.' with the understanding that vthe invention isy not confined to any strict conformity with the showing of the drawings but maybe changed and modiied so long as such changes and modications mark no material departure from the salient features of the invention as expressed ln the appended claims.

Y Referring to the drawings, whereinlike numerals refer to corresponding parts, the carton is (CIL 20G-44) such as cardboard which is provided with longitudinal score lines I, 2, 3, and 4 forming a bottom panel I2, side walls II and I3 and top marginal panels IIJ and I4.l The bottom panel I2 is scored adacent both ends along lines 'I to provide end flaps I8 which are free from the next adjacent flaps along slits 3|, 32 and 35 and 36, respectively, at each end of the bottom panel, and constituting inner closure flaps for the ends ofthe carton. Side walls II and ,I3'are scored adjacent their ends along lines 6 and 8, respectively, to provide outer closure flaps I6, I6', 20 and`20 which are free from the next adjacent flaps along slits 30, 33, 34 and 31.l Flaps I6 and 20 are provided with vided with slits 26 and 2l for receiving the tongue portions 25 when the carton is set up. Marginal tongue portions 25. Flaps I6 and 20' are' pro- Y panels I0 and I4 are provided with score lines 5 and 9, respectively, adjacent their ends for forming free end flaps I5 and `22 at their respective ends. A

A transparent sheet material 40 of suflicient width to overlap the marginal portions 4I and 42 of panels I0 and I4, is aiixed tothe panels III and I4 as shown in Figures 1 and 3. The transparent sheet material 40 is? preferably of sufficient length to extend the combined length of the marginal- Apanels and end aps I5 and 22 as shown in Figure 3.

In manufacturing the carton, the cardboard blank as illustrated in Figure 2, isfolded .on score line 3 so that panels I3 and I4 are in face contact soV with bottom panel I2 as shown in Figure 3. Panel I0 is then folded over on panel II along score line I and a transparent sheet 40 is then glued to the marginal portions 40 and 4I as shown in Figure 3. 'I'he carton so formed is shipped to the user in at knocked-down condition.

Infusing the carton for packaging goods therein, side walls II and I3 are olded up at right angles to the bottom panel as shown in Figure 4. 'Ihe goods to `be ypackaged are then inserted through the open ends of the carton and placed on the bottom panel I2 and beneath the transparent window 40. End flaps I8 are then folded up at right angles to the bottom panel as shown in Figure 4. Flaps I5 and 22, together with the ends y of the carton and interlocked by inserting tongue -25 through slit 26 as shown in Figure 6. 'I'he final package will then appear as shown in Figure 1.

The carton construction may be modled .in many ways. For example, the marginal top panels I0 and Il together with flaps I5 and 22 may be omitted and the transparent sheet may be used of such width that the longitudinal margins of same may be glued to the side walls II and I3. Free end portions may be provided on the transparent sheet which are adapted to be folded over the ends of the carton and retained in position by the end closures. These free end portions may be omitted if desired.

The carton construction may be modiiled in any suitable manner. For example, the irmer closure flaps I8 may be omitted if desired. The construction of the outer closure aps may also be modified if desired in any suitable manner other than that herein disclosed. If desired the end flaps I5 and 22 may be omitted and the free end portions of the transparent sheet are..

merely folded over the ends of the carton and retained in position by the outer closure flaps. It is therefore to be understood that the invention is not restricted to the particular construction of the blank yherein disclosed and that the principle of the window construction may be utilized on any suitably shaped blank.

The carton construction herein described provides a simple and economical construction requiring a amount of carton material as practically no stock is wasted in forming the carton. According to the construction of the present invention no windows are cut out of the body of the stock as is necessary in previous display carton constructions so that-there is a great saving produced in the manufacture of the cartons. Furthermore the present construction provides a very striking and eiIective display for the contents within the carton as a maximum visibility is provided since the window extends the full length of the carton and there is no obstruction at the ends of the window. The carton can also be readily packed with the goods to be packaged and it can be set up with speed without requiring any expensive equipment.

From the foregoing description it will be readily seen that there has been provided a display carton for the purpose set forth which is of unique and novel design, and in which the articles for sale may be kept on view and at the same time to be kept wrapped and clean.
